ASTM D7064/D7064M-08
(Practice)Standard Practice for Open-Graded Friction Course (OGFC) Mix Design
Standard Practice for Open-Graded Friction Course (OGFC) Mix Design
SIGNIFICANCE AND USE
The procedure described in this practice is used to design OGFC mixtures that will provide good performance in terms of permeability (tending to reduce hydroplaning and potential for skidding), and durability when subjected to high volumes of traffic.
SCOPE
1.1 This practice covers the mix design of open-graded friction course (OGFC) using the superpave gyratory compactor (SGC) or other suitable forms of compaction. The OGFC mix design is based on the volumetric properties of the mix in terms of air voids, and the presence of stone-on-stone contact. Information found in Guide D 6932 should be reviewed before starting the mix design. Where applicable, Specification D 3666 should be applied as a minimum for agencies testing and inspecting road and paving materials.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
